ductors and particularly that class of supports called trolley wireclamps.

' The object of my invention is to-produce a clamp whichwill support atrolley wire or other conductor from a hanger or other support, andwhich can be made to grip or relea'sethe conductor by moving thejawsinto or out of engagement with the con ductor and which is alin-ablewith respect to the conductor after having been installed upon thehanger or other support.

My invention resides in the new and novel construction or arrangement ofthe various parts more fully hereinafter describedand illustrated in theaccompanying drawing. 7 I

opening in which is positioned a pin 11. "The head 8 has secured theretoa lug 112 adapted to engage a lug 1'3 within-the re member 9 isrotatable relatively to the-supporting member 1 and islimited only bythe engagement of the lug 12with the lug1 3.

One method of securing the-parts '1 and 9 together is to form thesupporting member '1 opened or-expandedat the lower end that is easilydone in the art of casting, and then inserting therein the member 9 (seeFig. 3) andthen by mea'nsofpropertools such as dies, presses, etc. thelower-end of the member 1 is forced inwardly thereby securelylocking-the members '1 and 9 together in limited relative rotation. 'In

-Fig.'8 the heavy lines indicate the method in which the member'l may beoriginally fgrmed at the point 'X,and the dotted lines 1 show thecondition of the member latter Pivotally secured to the intermediate:member 9 are two jaws 14: each provided jaw is also provided with a lug16 which with a lip 15 arrangedto engage and lugs coact with theilugs 10and are held in relative operative: relation thereto "by means "otthepin 11. The'jaws 14 can" pivot rela 'tively to the intermediate member9about the axis of the pin 11, but can not rotate otherwise relatively tothe intermediate member -9. vIt will be evident therefore, that it thejawsletare grippedand rotated that the vmemberjj9 must rotatesimultaneously and 1 in "the same direction, and if "the rota tion iscarried sufficiently far in either direction the lug 112 will engagewith the} lug 13 and the rotation of the jaws will either be stoppedro-r,thevineniber 1' will be caused to rotate in the same direction. be.evident that the jaws are supported; from :It will 7 also the supportingmember-1 ;by:means of the intermediate,member-9.

The intermediate lluhreadablyymonnted :uponithesexteriorly threadedportion 550i thensupporting mem ber 1 isqangoperatingflimember 17w-hichawill rotate :irelative to' lJhBTHlGIlIbBI 1 and. :simultaneozusly movein either a'xial direction V and which is later turned inwardly ashereinafter more fully eXplainedc'The operating member '17 is providedwith an inwardly projecting annular flange 19 adapted to engage a groove20 in each jaw 14. The groove' member 17 is rotated that it willmoveupwardly or downwardly along the vertical axis and in so moving willcause the iaws 1 1 to be opened or closed depending upon the directionof movement of the member 17. It th'emember17 is moved downwardly theflange 19 will engage the lug 22 on each of the jaws and force the jawsinto engagement with-the trolley wire. If the operating member 17 ismoved upwardly the flange 19ewill engage the lug 21 on each of the jawsand move the jaws out of en gagement with the trolley wire or open themto receive a trolley wire. It will also be evident that whether the jawsare moved into or out of engagement with the trolley wire C that theyare permanently held in either an open or closed relation with respectto the trolley wire due to the novel interlocking of the parts 14 and17.

V In assembling the various parts of my in-.

.vention the members 1 and 9 arefirst assembled as herein described orby other methods, after which the member 17 is threaded on tothe member1 and as the flange 18 projectsupwardly as indicated by 18 the member17v can be threaded on ,to the member 1 to a much greater'distance thanshown in Fig. 4. This will permit the aw members 14 to be positioned inplace and the pin 11 inserted'in position. The operating member 17 isthen rotated and moved downwardly on the member 1 a distance suflicientand the upstanding flange 18' is rolled or swagedinwardly as shown bythe numeral 18 after which operation it will be impossible for theoperating member 17 to be raised a sufiicient distance to per mitthe'pin 11 to be withdrawn as the flange 18 will engage the flange 3before the flange 19 has raisedabove the upper edge of the trolley wire.

I In the installation of my invention the hanger H is presumed to bepositioned in p'lace'and the clamp is then taken and by means of thejaws 14: rotated into the position shown in Fig. 3. Rotation of themember 1 is brought about as previously described and if the jaws 14: donot-aline with the trolley wire C it is then possible to back ofithejaws until thelips 15aline with the The alinement having been broughtabout, the trolley wire is held in position between the jaws manuallyand the operating member '17 rotated in the proper direction to movethelips 15 toward each other until they grip the conductor. A wrench orother tool then applied to the operating member 17 will force the jawsinto a secure gripping engagement with the trolley wire andhold thetrolley wire securely.

In Fig. 6 is shown by relation of the lugs 13 and 12' how the lugs arerelated when the part 1 is being rotated by means of the part 9, and therelation shown by the lugs 12 and 13 indicate the position which may betaken by the lugs after the jaws have been reversely rotated in order toaline the jaws with the trollev wire. 7

By omitting the lugs 12 and 13 the jaws and member 9 are made to rotaterelative to the member 1 without limit and in that case the device canbe secured to a hanger by the application of a wrench to the flange 3.

There are undoubtedly modifications Which will be apparent to thoseskilled in the art, therefore, I do not wish to be limited otherwisethan by my claims.
